material into the fork of D the cross-movement of E strikes the materialabove D and bends it over in such a manner that the upward movement of Dpicks up the bight, so that the material may now lead from the nettingat A A to the projection E thence to the fork D thence through 0 to B BFifth, the sliding bar F, with the projec tions F is operated, by meansof the lever F and cam F in a direction parallel to E, the projectionsstriking the portion of the material between E and D carrying it over toone side, but which at the same time is prevented by the'furthermovement of B B from interfering with the material between D and B B, atwhich time E, by a reverse motion, carries its bight back under theportion of the material between D and B B being, by the same forwardmovement of the latter, prevented from interfering therewith, so thatthe material may pass from the netting at A A to E thence to D thence toF, thence over itself to B B as seen in position 2 of Fig. 6. The motionof B B is now reversed, laying the material back against itself, andinto the range of motion of F (as seen in position 3, Fig. 6,) which, bya reverse motion, leaves the bight it held, and, striking the part ofthe material between D and B B draws that bight out through the loopagainst which it lies, making a perfect knot, which, by the third motionof E and the continued motion of F, is opened ready for the passage ofthe shuttle. (See Fig. 6, position 4.) The material then passes from thenetting at A A to E thence to D thence around the part from A A to E andthrough between that and the part from E and D to F; then back throughand between the same parts to E, thence through 0 to B 13*. These knotsare formed right and left, in alternate sucession, by the motion of Eand F and their cams, with which they are connected.

Sixth, the triple sliding bar or guard G,

which, by means of the connections G G levers G and cam G is movedbackward and forward across the path of E and F, and, when broughtforward, throws the material off of and holds it clear of E and F (seeFig. 6, position 5,) thereby facilitating the drawing up of the knot,which being accomplished, it returns to its normal position. v

The shuttle-movements consist of First, a series of shuttles orcarriers, H, H, containing the portion of the material which passesthrough the open knots orfilling. These carriers are made of metal orother suitable material, tapered toward each end, and with an opening orsocket in the bottom, near each end. These shuttles are supported by thecarriages H H the latter having trunnions formed upon them, by whichthey are supported on the arms H H of the rock-shafts H H, and, by meansof the devices or connections H H, levers H H and cam H receive theirproper motion. The carriages H H are steadied in their position by meansof the devices H H and arms H H so that, when the carriage H movesforward by the action of the cam H", it also rocks upon its trunnions,and the same result is produced upon the carriage H The carriages H Hhave. each of them, a series of sockets, constructed and fitted toreceive the ends of the shuttles H H, and also a series of projectionsadapted to fit into the openings or sockets in the bottom of theshuttles H H, the whole being constructed and arranged in such a mannerthat while the open knots are being formed the shuttles are held by oneor the other of the carriages H H alternately, one end of each carrierbeing in the socket of the carriage, and the projection of the carriagebeing in thesocket of the carrier. When the open knot is ready, asbefore described, (see Fig. 6, position 4,) the carriage, having thecarriers attached, moves forward, tipping as it moves, passing the endsof the shuttles through the open knots before them, and into the socketsof the other or opposite carriage, and continuing its motion, tippingits projections out of the sockets of the carriages, leaving them freeto be drawn out of the sockets of the carriage supporting them, by theopposite'carriage, to which they become attached, and which starts back,at the same time tipping, so that the shuttles become connected with thelast-mentioned carriage by means of the sockets and projections abovedescribed, and being drawn, by a positive motion from the firstcarriage, out through the knot, and held there until the next knot isprepared, when they are returned throughthe newly-formed knots to thefirst or opposite carriage, in the same manner as they were passedthrough the last, each shuttle engaging, by the action of E and F, withthe material to the right or left of that it engaged before, forming acontinuous Web or net, making the diagonal mesh with a single passage ofthe shuttle through the knot or bend.

The draw-up movement consists of the straight-edges J 1 J hingedtogether in such a manner as to permit the material to pass between themfreely when open, but, when at work, closing upon it with firmness,increased by the strain upon it. The edge J is 'firmly secured to theshaft J which rocks, carrying with it J J The shaft J is rocked by thesegment J, the rack J the lever J and cam J J is hinged to J at j, andheld close to it by means of the springs J J. J is capable of extensionfrom the center by means of the, slots and screws J J?, and the two areso placed that, while the open knot is being formed, J rests against theprojection J which holds it off of J, so as to allow the material topass freely; but when the knot is formed and the shuttle passed, (seeFig. 6, position 5,) the cam J causes the. shaft J to rock, carryingwith it J 1 J As J leaves the projection J it closes, by the action ofthe springs J upon the material, carrying it forward and drawing theknot to any desired 1 degree of tension, returning aud opening in timefor the formation of the next knot.

. The meshrmovements consist of l First, the straight roller1K, soarranged 1 the screws K K, asmay be required.

. Second, the straight-edgesI L, which are r 3 so hinged together as toadmit of opening and l j .1 allowing the netting to pass freely, orclosing .1 firmly, andholding the netting while the knot is being drawnup by J I. The edge L is made to slide by means of the connections ,ordevices I1 L levers L L, and cam L .1. [During the time the knot isbeing formed, a the shuttle; passing, and the knot drawncup, L L? standforward, closed. and held together by the stationary cam-pieces LiL thenetting gybeing held firmly between them but after {the knot isdrawn upthe cam L causes L L to slide back, drawing thenetting up between 1 MAlAand over. K, until Ustrikes the adjusti able cam-pieces I L",fwhichopens L? and L and they return open and without action upon the nettinguntil closed by L The size of the mesh is governed by-the distancetraversed yby L L before being opened by L" L", which aresecuredbyscrews andtslots, sothat they scan be set at auy d'esire'ddistance from the ormal position of L L ,.thereby' making the mesh largeor small, at pleasure.

Third, the threerolls M M M M is sup ported by stationary bearings, andis turned by i r the pulley M belt M?, and pulley M on the main shaft. Mis supported by a frame,M, which l 1 is so arranged as to'rock on thesame center l as Mkand is'revolved by the pulleys and belt 1 l M M M3rests 'uponlM and M and is steadied in position by the guides M M of theframe M, in such a manner that it may be lifted at will. M and M are alittle more than overbalanced by the weights. M M so that, (while thenetting passesybetween M and M y or winds up on M the action of therolls will i 1 always keep the desired tension upon the neti ting,taking it up as the edges L L move forward, and holding it as theyreturn.

that it may be raised onlowered by means of 7 It the netting is rolledupon Mflthe arrangement of the guides M is such that the larger the rollbecomes, the more nearly its center empty one. As the roll M is filled,it is reremoved and another substituted for it without delay or change,except to cut the netting.

- -What I claim as my invention is v 1. The machine constructedsubstantially as described, and operating to form netting of thedescription known as the diagonal mesh and fishermans bend, and by asingle passage of the shuttle.

2. The shuttles H H, in combination with theirsupports or carriages H H,when constructed and operating in the manner and for the purposes hereindescribed.

3. The arrangement and combination of the cam J its arm or lever J rackJ segment J and shaft J with the straight-edges J J in the manner andfor the purpose herein described.

4; The sliding carriage L with its straightedge, in combination with themovable clamping-bar L, the latter being operated by cams L and L as andfor the purpose set forth.

5. The weighted rocking frame M and rollers M and M arranged upon ashaft, to the.

end of which is attached a pulley, operated by means of the pulley M anda belt connecting the two pulleys, in. the manner and for the purposeherein shown and described.

6. The arrangement and combination of the bar D and its forks D with thesliding barsE and F, when the bars E and F have formed upon themprojections, in the manner and for the purpose herein described.
